Anxiety can affect your digestive system and may cause symptoms that include discomfort and nausea.

Anxiety is a response to stress, and it can cause a variety of psychological and physical symptoms.

When you feel overly anxious, you might notice that your heart rate speeds up and your breathing rate increases. And you might experience a bout of nausea.

During a moment of high anxiety, you might feel just a bit queasy. It’s that “butterflies in the stomach” feeling that you might have before giving a public presentation or going on a job interview. This kind of nausea may pass fairly quickly.

But sometimes, anxiety-related nausea can make you totally sick to your stomach. Your stomach churns so much that you have to make a dash for the bathroom. You may even reach the point of dry heaving or vomiting.

Everyone feels anxiety occasionally. It’s not abnormal and not necessarily a bad thing. But it can be problematic if you frequently feel anxiousness accompanied by nausea.

Read on as we explore anxiety-related nausea, ways to manage it, and when it’s time to see a doctor.

Anxiety can trigger your fight, flight, or freeze response. Basically, your body is preparing you to face a crisis. This is a natural reaction to a stressful situation and, when called for, can help you survive.

When you feel stressed or anxious, your body releases a rush of hormones. Neurotransmitters in the brain react by sending messages to the rest of your body to:

  • get the heart pumping faster
  • increase the breathing rate
  • tense the muscles
  • send more blood to the brain

Anxiety and stress can affect virtually every body system. This includes your cardiovascular, endocrine, musculoskeletal, nervous, reproductive, and respiratory systems.

In the digestive system, stress can cause:

  • nausea, vomiting
  • heartburn, acid reflux
  • stomachache, gas, bloating
  • diarrhea, constipation, painful spasms in the bowel

If you’re one of the 7 to 16 percent of Americans who have irritable bowel syndrome (IBS) or the 12 percent who have chronic upset stomach, feeling anxious might prompt symptoms like nausea and vomiting.

anxiety disorders that may cause nausea

If you’re having this type of response often or for no apparent reason, it can negatively affect your quality of life.

Anxiety disorders that aren’t addressed can lead to other conditions, such as depression.

The symptoms you feel due to anxiety are very real. Your body is responding to a perceived threat.

Assuming that it’s not a true emergency situation, there are some things you can do to help to control anxiety and nausea.

Coping with anxiety

When anxiety takes hold, try to focus on the present rather than stressing about what may happen later.

Consider what’s happening in the moment, and remind yourself that you’re safe and that the feeling will pass.

Take long, deep breaths. Or try to distract yourself by listening to your favorite song or counting backward from 100.

It takes time for your body to get the signal that you’re not in immediate danger, so don’t be too hard on yourself.

Ways to cope with anxiety

There are also a few things you can do to cope with anxiety in the long term, such as:

If you have chronic anxiety, see your primary care physician for a thorough checkup. Your doctor can refer you to licensed professionals who can help determine your triggers, address your anxiety issues, and teach you how to keep it from spiraling out of control.

What to do when nausea hits

Try these when you feel nauseated:

  • Drink water and other clear liquids in small sips to replenish lost fluids.

In the long term:

  • Try to avoid heavy, greasy foods.
  • Stay hydrated, but limit alcohol and caffeine.
  • Eat smaller meals throughout the day rather than three big meals.

If you frequently need over-the-counter nausea medications or vomit often, talk with your doctor.
